SPINDLE FOB HOLDING MUSIC-SPOOLS.

Specification of Letters Patent. Application filed November 1, 1911. Serial No. 657,997.

Patented June 1913.

1 '0 all'whom it may concern:

Be it"known that (I, H'nnnnn'r J. La'Jouc, a citizen'of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented a new and useful Spindle for Holding Music-Spools, of which the following is a specification.

The objectof. this invention is to provide a new and improved spindle for holding the music rolls or spools on which the long perforateol note-sheets employed in musical 1nl strnnients are Wound. Music spools 0t this I character as now generally constructed have socket pieces axially fitted into their ends and the right end of each spool is provided With-a notch or mortise. The instruments in which such music spools are employed are provided with two spindles, the left-hand spindle being spring-pressed and the righthand spindle being provided with a tenon or irregularly shaped projection to engage into the mortise or notch in the right-hand end of the spool. The music spool runs idly on said spindles. as the note sheet is drawn therefrom for playing, and power is impartedto the righthand spindle when the note-sheet is tobe rewound on the music spool atter playing, the said mortise and tenon forming a connection by which power is imparted to the spool. The spool is in serted in position by placing one of the socket pieces on, one of the spindles and then snapping the other socket piece on the other spindle. It happens quite frequently in insorting the spool in position in tins n'ranner that the mortise and tenon do not properly register and the muslc spools held too lar to the left as the note-sheet is unwound therefrom, thus causing a displacement in the note-sheet which does not produce ac The unwinding of, the note music spool 'does not tend to the right-hand-spindle turns sheet from the correct this, as

'ireely when the ndte-shect isunwound. To

correct this diiliculty I make the tenon or projection of the right-hand spindle relatively movable thereto and provide the same with a light, spring tending normally to force the same outward. By this arrangement, when the music spool is placed botween the two spindles it will assume its proper position laterally, even it it is not' placed in position so that the mortise in the spool matches with the tenon oirtlic righthand vspindle. If the music spool be placed in position between the spindles without the tcnon and mortise matching, ust as soon as there is the proper amount of slip between the music spool and the right-hand spindle so that the mortise and teuon will match (which may occur as the music sheet is turned forward, or as the rewinding is co1nmenccd), the tenon will spring into the mortise and the spool will be positively engagcd with the right hand spindle so that the power can be imparted thereto for re winding.

The invention is illustrated in the ac'com' pauying drawing, referring to which,

Figure l is an elevation partly in section;

illustrating tln l'ronl ot' the spool box showing how my invention is applied. Fig. 2 is a sectional elevation on an enlarged scale of theright-hand spindle. Fig. 3 is an end elevation thereof. Fig. 'lis an end eleva: tion on an enlarged scale of the end of the music spool, and Fig. 5 is a sectional elevaiicn thereof.

Referring to the drawing and in detail, A designates the frame of a spool box in which the supporting spindles are mounted.

B designates the 1eft-hand spindle. The spindle fits in a casing or tube 10 inserted in the wall of the spool box. The spindlewis reduced in diameter and surrounding the same is a spring 11 which tends normally'to force the spindle B outwardly. The spring bears at its rear end on a bushing-12 in sorted in the tube 10. The reduced portion of the spindle projects outwardly through the bushing and is provided at its end with a cap or nut 15-) which limits the outward movement of the spindle. The construction described is one of the ordinary or approved 'constrin-iimi o't left-handspindle now employed. l

The right-hand spindle in which my invention is embodied comprises a shaft 14 on the end of which is fitted a collar 15, the end of the shaft and the collar being inserted into a bushing 16 and held in place therein by a suitable pin 17. The bushing 16 thus comprises the supporting part of the right-hand spindle. The end of the hushing is provided with an oblong orifice and .lilting in the same is a tcnon or projection This icnon is provided with a collar ll) on its inside and a light spring 20 is arranged between the end of the shaft Hand collar 15 and the collar 19' and thus tends normsillyto force the tenon outwardly. The

shaft 14 is journaled in suitable bearings in the spool box frame A and 1n a bracket car- 'ried thereby and the usual sprocket wheel or gear 21 is arranged thereon so that power can be applied to the shaft 14. to rewind the note-sheet on the musicspool.

C designates the musicspool onwhich the perforated note-sheet D is -wound. The music spool is provided withrecessesaxially in its ends, and-sockets or rings 22 or 23 are driven therein,".the right-hand ring usually being made longer than the left-hand ring. The right-hand end of the music spool isspindle and the music spool soasto bring ,the tenon and mortise into register, the ,tenon'will snap into the mortise. This locking'willtake place automatically and will' not cause any disturbance of the lateral position of the music spool. Vhn the parts arelocked in this manner, the note-sheet can be rewound on'ithe'music spool' by the 'apv "plioation of power to the sprocket wheel or gear 21. I f details and arrangements herein shown and described, andparticularlythe The shape of the mortise and tenon,-- can be varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims. I I

Having'thus fully described my invention,

1 what I claim and desire to secure by Letters Patent is 1 the end 'ther eof a socket and a mortise,"co1nprising a bushing for engaging 1nto the socket to. center the spindle and guide it into proper position with respect. to the spool,

By the arrangements describe d, theinusic l. .A spindle for a music spool having in 7 and a spring-pressed axially moving tenon housed in said'bushing. H

2. In a spindle'for a music spool having a socket and a mortise extending inwardly from the endof the socket comprising a- .shaft having a bushing on its end for. en-

gaging into and fitting the socket, and a spr ng pressed axially moving tenon housed beyond it into the m'ortise.

3. A spindle for', a mus c 'spool having a 111 said bushing. and adapted to be projected socket and a mortise, comprising a. bushing for engaging-intoth socket and having an oblong opening, a tenOn'prO ectmg through said opening and a spring forpressing the tenon normally outwardly.

A spindle for a music spool having a socket and a mortise, comprising a shaft, a busliing'secured on the end thereof for fitting intosaid socket, and having an oblong opening, a tenon pro ec-t1n'g through said opening and having a collar, and a spring housed .in said bushing and'tending normally to fore the tenon outwardly. v

5. A spindle tora music spool having a socket" and a'i'inoi tist comprising a springpressed'spindle for engaging one end'of the music spool anda bushing for engaging into the socket at the other end of the spool carrying a-spring-pressed tenon for engaging into the mortise, the spring acting on the spindle having a heavier'tension than thespring actmg on the tenon.
